The Principal Diseases of Lower Vertebrates presents the material published by Heinz H. Reichenbach-Klinke between 1957 and 1962 in three separate volumes as ""Krankheiten der Aquarienfische"" (Alfred Kernen, Stuttgart), ""Krankheiten der Amphibien,"" and ""Krankheiten der Reptilien"" (Gustav Fischer, Stuttgart). The scope of the work has been enlarged with material contributed by E. Elkan who has also done the translation. Representatives of the main groups of parasites affecting fish have been presented as far as possible. The book is organized into three parts covering the diseases of fishes, amphibians, and reptiles. Experience has shown that those who keep, or are interested in, one kind of lower vertebrate will sooner or later also take an interest in one of the other groups. It was therefore thought expedient to include what is at present known of lower vertebrate pathology in one volume, even at the risk of some repetition where fishes, amphibians, and reptiles suffer from similar diseases or are the victims of identical parasites.

This work is designed to introduce veterinary practitioners to the diagnosis and treatment of disease in captive amphibians. It covers various aspects of amphibian captive husbandry and propagation while providing the reader with a foundation on which to evaluate a given husbandry routine. The diagnosis of disease in amphibians by the application of basic clinicopathologic techniques is discussed, and infectious, metabolic, nutritional, neoplastic and idiopathic disorders of amphibians are also covered.

This is the first book on ranaviruses. Ranaviruses are double-stranded DNA viruses that cause hemorrhagic disease in amphibians, reptiles, and fish. They have caused mass die-offs of ectothermic vertebrates in wild and captive populations around the globe. There is evidence that this pathogen is emerging and responsible for population declines in certain locations. Considering that amphibians and freshwater turtles are suitable hosts and the most imperiled vertebrate taxa in the world, ranaviruses can have significant impacts on biodiversity and ecosystem function. Additionally, many fish that are raised in aquaculture facilities and traded internationally are suitable hosts; thus, the potential economic impact of ranaviruses is significant. Ranaviruses also serve as a model for replication and gene function of large double-stranded DNA viruses. There is an urgent need to assemble the contemporary information on ranaviruses and provide guidance on how to assess their threats in populations. Through the Global Ranavirus Consortium, 24 experts from six countries were organize to write this volume, the first book on ranaviruses. The book begins with a discussion on the global extent of ranaviruses, case histories of infection and disease in ectothermic vertebrates, and current phylogeny. Basic principles of ranavirus ecology and evolution are covered next, with a focus on host-pathogen interactions and how the virus emerges in its environment. There are two chapters that will discuss the molecular biology of ranaviruses, host response to infection, and the genes responsible for immune system evasion. One chapter establishes standards for testing for infection and diagnosing ranaviral disease. The book ends by providing guidance on how to design ranavirus surveillance studies and analyze data to determine risk, and discussing the role of the Global Ranavirus Consortium in organizing research and outreach activities.

- A hypothesis is a proposition, set forth as an explanation for the occurrence of a phenomenon, that can be tested. - The basis for scientific investigation is the collection of information to formulate and test hypotheses. - Experimental methods measure the effect of manipulations caused by the investigator; observational methods collect information about naturally occurring events. - There are three sub-types of experimental techniques that differ in the way subjects are chosen for inclusion in the study, in the amount of control that the investigator has over variables, and in the method used to assess changes in other variables. - Descriptive observational studies dominate the early phase of most investigations and involve the description of disease-related events in the population. Associations among factors may be observed but the strength of the associations is not measured. - Analytical observation al techniques are of three basic types: prevalence surveys, case:control studies, and incidence or cohort studies. All attempt to explain the nature of relationships among various factors and to measure the strength of associations. - Prevalence surveys and case:control studies deal with disease existing at the time of the study; incidence studies are concerned with the development of disease over time. - Observational studies may be retrospective, using existing data, or prospective with collection of new information.

Attention to viral infections and pathology previously focussed on diseases of economically important fish. In recent years, however, much new information on molecular virology and oncogenicity derives from viruses occurring in amphibians. New insights into the field of zoonosis were gained by studies of lower vertebrates serving as intermediate hosts in multiple human infections. Certain viruses, e.g. the influenza virus or calicivirus, seem capable of bridging species lines and even the land - sea interface. Global developments in aquaculture are indicated in influenza pandemics. These proceedings present research findings on viruses of fish, amphibians and reptiles, including defence mechanisms, zoonoses, evolutionary considerations and diagnostic approaches.

The book will cover the most important zoonoses with a public health impact and debate actual developments in this field from a One Health perspective. The outline of the book follows a “setting” approach, i.e. special settings of zoonoses with a public health aspect, rather than presenting a simple textbook of an encyclopedic character. Main chapters will deal with zoonoses in the food chain including a special focus on the emerging issue of antibiotic resistance, with zoonoses in domestic and pet animals, in wildlife animal species (including bats as an important infectious agent multiplier), influenza and tuberculosis as most prominent zoonoses, and zoonotic pathogens as bioterroristic agents. Special interest chapters debate non-resolved and currently hotly debated zoonoses (e.g. M. Crohn/paratuberculosis, chronic botulism) as well as the economic and ecological aspects of zoonoses.
